Lung tumor; A chest X-ray showing a tumor in the lung (marked by arrow) Specialty: Oncology Pulmonology: Symptoms: Coughing (including coughing up blood), weight loss, shortness of breath, chest pains [1] Complications: Lung cancer: Causes: Smoking Radon gas Asbestos Air pollution Genetics
A lung nodule or pulmonary nodule is a relatively small focal density in the lung. A solitary pulmonary nodule (SPN) or coin lesion, [1] is a mass in the lung smaller than three centimeters in diameter. A pulmonary micronodule has a diameter of less than three millimetres. [2] There may also be multiple nodules.
Pulmonary function: increased residual volume, increased total lung capacity, fixed obstruction, low diffusing capacity of the lung for carbon monoxide that corrects with alveolar volume High-resolution CT scan: diffuse pulmonary nodules 4–10 mm, greater than 20 nodules, mosaic attenuation or air trapping in greater than 50% of the lung
Other causes of lung cancer-associated shortness of breath can be treated directly, such as antibiotics for a lung infection, diuretics for pulmonary edema, benzodiazepines for anxiety, and steroids for airway obstruction. [51] Up to 92% of those with lung cancer report pain, either from tissue damage at the tumor site(s) or nerve damage. [54]
DPB causes severe inflammation and nodule-like lesions of terminal bronchioles, chronic sinusitis, and intense coughing with large amounts of sputum production. The disease is believed to occur when there is susceptibility, or a lack of immune system resistance, to DPB-causing bacteria or viruses , caused by several genes that are found ...
Caplan syndrome presents with cough and shortness of breath in conjunction with features of rheumatoid arthritis, such as painful joints and morning stiffness. Examination should reveal tender, swollen metacarpophalangeal joints and rheumatoid nodules; auscultation of the chest may reveal diffuse crackles that do not disappear on coughing or taking a deep breath.
Pulmonary laceration is usually accompanied by hemoptysis (coughing up blood or of blood-stained sputum). [12] Thoracoscopy may be used in both diagnosis and treatment of pulmonary laceration. [8] A healing laceration may resemble a lung nodule on radiographs, but unlike pulmonary nodules, lacerations decrease in size over time on radiographs. [4]
Hemoptysis may be exacerbated or even caused by overtreatment with anticoagulant drugs such as warfarin. [ citation needed ] Blood-laced mucus from the sinus or nose area can sometimes be misidentified as symptomatic of hemoptysis (such secretions can be a sign of nasal or sinus cancer , but also a sinus infection ).
